How Banks Work

The capital requirements to start a bank often vary greatly from state to state. In Florida, the suggested capital requirement is $6 million for a bank in a metropolitan area and $4 million for a bank in a rural area. In other states, such as New York, that amount might be $10 million or more for metropolitan areas. Those capital requirements are usually determined by your strategic plan and pro forma financial statements for the market you've selected.

As mentioned above, the organizing group may be responsible for 10 percent to 15 percent of that amount. The remainder is sold to shareholders. Organizing groups may shoot for 400 to 750 or more shareholders in order to raise the money needed to start the bank. Usually, the more shareholders a bank has, the better its chance of succeeding.
